No endless tracking. Just a clear plan that moves your bedtime and wake time closer to your goal — 15 minutes at a time. Tell Phase when you currently sleep, when you want to sleep, and it builds a personalized day-by-day plan to get you there.

About

TrendCut

TrendCut shows the weight trend under the daily noise. A weigh-in can swing with water, salt, sleep or a late dinner. None of that is fat gain. TrendCut runs every weigh-in through a statistical trend engine, so you can see the direction you are actually moving. Your raw entries are never deleted or rewritten. WHAT YOU GET • Trend chart: a smoothed trend line over your daily entries, with a shaded confidence band and your goal line. • Your real rate of change: weekly change read as a rate, in kg or lb per week, not yesterday minus today. • Plateaus, recognised early: TrendCut calls out an active plateau instead of leaving you to guess whether flat weeks mean anything. • Confidence, stated out loud: every read carries a confidence level and the reason for it. Sparse data lowers confidence; it never sharpens the verdict. • Context tags: mark travel, salt, training or illness so a spike has an explanation. • Sunday weekly report: a frozen summary of trend, weekly rate and goal progress with a short plain-language read. BRING YOUR HISTORY WITH YOU Import your weight history from Apple Health, or from a CSV file exported by another weight app. Export your data to CSV whenever you want, free. Your history stays yours. NO STREAKS. NO SHAME. No badges, no confetti, no streak to protect, no red number punishing a bad morning. Weight is data, not a moral score. WORKS WITHOUT AN ACCOUNT Everything is stored on your device first. Sign in only if you want your data backed up and synced across devices, and delete your account from inside the app whenever you want. FREE AND PREMIUM The trend read always stays free: the honest trend, its direction and its confidence. Premium adds depth, not truth. With Premium, Clarity adds an estimated arrival month for your goal. Premium also adds week-over-week changes, plateau and phase detection, a maintenance-calorie estimate, and longer chart ranges. Optional tips are available if you want to support the app. They change nothing in the app. Subscription and purchase options are shown in the app before you buy. Subscriptions renew automatically unless auto-renew is turned off at least a day before the end of the current period; payment is charged to your Apple Account at confirmation of purchase. Manage or cancel in your Apple Account settings. PRIVACY Your health data is never used for advertising and is never sold.
